About Me

I'm passionate about designing and building custom hardware solutions, from smart home devices to specialized electronics. Every project is a learning experience, and I love the challenge of turning ideas into working PCB designs.

Currently exploring automotive embedded systems with a focus on wireless communication protocols and LED control systems. My work spans from schematic capture and PCB design through firmware development and real-time system integration.
